* Fixed an irq problem in the cave driver which was freezing esprade at the 1st boss. The cause is the new version of starscream which is more precise with interrupts, I even wonder how the cave driver could work the way it was before that... anyway it's fixed, but it could happen in some other raine games (luckily very few drivers have a complicated interrupt system like the cave driver). * The recent gui changes could make some part of the gui to remain visible after a game had been started... lack of tests here, sorry !
